Alternatives to Carvana, shift, and vroom?

tried selling a 2017 hyundai sonata base plugin with only 28k miles, AlGo came in at $17,800.00, but claims that they do not come to california!
carvana$15,660.00
carmax$13,600.00
99drive soft offer$17,000.00
shift does not deal with hyundai motor finance
multiple chevy dealers offered$16,000.00
my payoff is $17,302.67, any other suggestions?
